- Sections or subsections omitted from the full prescribing information are not listed.
- 1 INDICATIONS AND USAGE
BETOPTIC S® Ophthalmic Suspension 0.25% is indicated for the treatment of elevated intraocular pressure (IOP) in patients with chronic open-angle glaucoma or ocular hypertension.Close
- 2 DOSAGE AND ADMINISTRATION
Instill one drop of BETOPTIC S Ophthalmic Suspension 0.25% in the affected eye(s) twice daily. BETOPTIC S may be used alone or in combination with other IOP lowering medications.Close
- 3 DOSAGE FORMS AND STRENGTHS
Bottle filled with 10 and 15 mL of 0.25% sterile ophthalmic suspensionClose
- 4 CONTRAINDICATIONS
BETOPTIC S Ophthalmic Suspension 0.25% is contraindicated in patients with:
- sinus bradycardia
- greater than a first degree atrioventricular block
- cardiogenic shock
- patients with overt cardiac failure
- hypersensitivity to any component of this product.
- 5 WARNINGS AND PRECAUTIONS
As with many topically applied ophthalmic drugs, this drug is absorbed systemically. The same adverse reactions found with systemic administration of beta-adrenergic receptor inhibitors may occur with topical administration. For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and death due to cardiac failure, have been reported with topical application of beta-adrenergic receptor inhibitors.
5.2 Cardiac Failure
BETOPTIC S Ophthalmic Suspension 0.25% has been shown to have a minor effect on heart rate and blood pressure in clinical studies. Caution should be used in treating patients with a history of cardiac failure or heart block. Treatment with BETOPTIC S Ophthalmic Suspension 0.25% should be discontinued at the first signs of cardiac failure.
5.3 Diabetes Mellitus
Beta-adrenergic receptor inhibitors should be administered with caution in patients subject to hypoglycemia or to diabetic patients (especially those with labile diabetes) who are receiving insulin or oral hypoglycemic agents.
Beta-adrenergic receptor inhibitors may mask the signs and symptoms of acute hypoglycemia.
Beta-adrenergic receptor inhibitors may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Patients suspected of developing thyrotoxicosis should be managed carefully to avoid abrupt withdrawal of beta-adrenergic receptor inhibitors, which might precipitate a thyroid storm.
5.5 Muscle Weakness
Beta-adrenergic receptor inhibitors have been reported to potentiate muscle weakness consistent with certain myasthenic symptoms (e.g., diplopia, ptosis and generalized weakness).
5.6 Surgical Anesthesia
The necessity or desirability of withdrawal of beta-adrenergic receptor inhibitors prior to major surgery is controversial. Beta-adrenergic receptor inhibitors impair the ability of the heart to respond to beta adrenergically mediated reflex stimuli. This may augment the risk of general anesthesia in surgical procedures. Some patients receiving beta-adrenergic receptor inhibitors have experienced protracted, severe hypotension during anesthesia. Difficulty in restarting and maintaining the heartbeat has also been reported. In patients undergoing elective surgery, consider gradual withdrawal of beta-adrenergic receptor inhibitors. If necessary during surgery, the effects of beta-adrenergic receptor inhibitors may be reversed by sufficient doses of adrenergic agonists.
5.7 Bronchospasm and Obstructive Pulmonary Disease
Caution should be exercised in the treatment of glaucoma patients with excessive restriction of pulmonary function. There have been reports of asthmatic attacks and pulmonary distress during betaxolol treatment. Although re-challenges of some such patients with ophthalmic betaxolol has not adversely affected pulmonary function test results, the possibility of adverse pulmonary effects in patients sensitive to beta-adrenergic receptor inhibitors cannot be ruled out.
While taking beta-adrenergic receptor inhibitors, patients with a history of atopy or a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated accidental, diagnostic, or therapeutic challenge with such allergens. Such patients may be unresponsive to the usual doses of epinephrine used to treat anaphylactic reactions.
5.9 Angle-Closure Glaucoma
In patients with angle-closure glaucoma, the immediate treatment objective is to reopen the angle. This may require constricting the pupil. Betaxolol has little or no effect on the pupil and should not be used alone in the treatment of angle-closure glaucoma.
5.11 Bacterial Keratitis
Bacterial keratitis may occur with use of multiple dose containers of topical ophthalmic products when these containers are inadvertently contaminated by patients who, in most cases, had a concurrent corneal disease or a disruption of the ocular epithelial surface. Instruct patients on appropriate instillation techniques [see Patient Counseling Information (17)].
5.12 Choroidal Detachment
Choroidal detachment after filtration procedures has been reported with the administration of aqueous suppressant therapy.
- 6 ADVERSE REACTIONS
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical trials, the most frequent adverse reaction associated with the use of BETOPTIC S Ophthalmic Suspension 0.25% has been transient ocular discomfort. The following other adverse reactions have been reported in small numbers of patients:
Ocular: blurred vision, corneal punctate keratitis, foreign body sensation, photophobia, tearing, itching, dryness of eyes, erythema, inflammation, discharge, ocular pain, decreased visual acuity and crusty lashes.
Systemic adverse reactions include:
Cardiovascular: Bradycardia, heart block and congestive failure.
Pulmonary: Pulmonary distress characterized by dyspnea, bronchospasm, thickened bronchial secretions, asthma and respiratory failure.
Central Nervous System: Insomnia, dizziness, vertigo, headaches, depression, lethargy, and increase in signs and symptoms of myasthenia gravis.
Other: Hives, toxic epidermal necrolysis, hair loss and glossitis. Perversions of taste and smell have been reported.
In a 3-month, double-masked, active-controlled, multicenter study in pediatric patients, the adverse reaction profile of BETOPTIC S Ophthalmic Suspension 0.25% was comparable to that seen in adult patients.
6.2 Additional Potential Adverse Reactions Associated with Betaxolol
Additional medical events reported with other formulations of betaxolol include allergic reactions, decreased corneal sensitivity, corneal punctate staining which may appear in dendritic formation, edema and anisocoria.
- 7 DRUG INTERACTIONS
7.1 Oral Beta-Adrenergic Receptor Inhibitors
Patients who are receiving a beta-adrenergic receptor inhibitor orally and BETOPTIC S Ophthalmic Suspension 0.25% should be observed for a potential additive effect either on the IOP or on the known systemic effects of beta blockade.
7.2 Catecholamine-Depleting Drugs
Close observation of the patient is recommended when a beta-adrenergic receptor inhibitor is administered to patients receiving catecholamine-depleting drugs such as reserpine, because of possible additive effects and the production of hypotension and/or bradycardia which may result in vertigo, syncope, or postural hypotension.
7.3 Concomitant Adrenergic Psychotropic Drugs
Betaxolol is an adrenergic receptor inhibitor; therefore, caution should be exercised in patients using concomitant adrenergic psychotropic drugs.
7.4 Calcium Antagonists, Antiarrhythmics and Digitalis
The concomitant use of a beta-adrenergic receptor inhibitor with calcium antagonists, antiarrhythmics (including amiodarone) or digitalis may have additive effects resulting in hypotension and/or marked bradycardia.
- 8 USE IN SPECIFIC POPULATIONS
Pregnancy Category C: Reproduction, teratology, and peri- and postnatal studies have been conducted with orally administered betaxolol HCl in rats and rabbits. There was evidence of drug related postimplantation loss in rabbits and rats at dose levels above 12 mg/kg and 128 mg/kg, respectively. Betaxolol HCl was not shown to be teratogenic, however, and there were no other adverse effects on reproduction at subtoxic dose levels. There are no adequate and well-controlled studies in pregnant women.
BETOPTIC S Ophthalmic Suspension 0.25% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
8.3 Nursing Mothers
It is not known whether betaxolol HCl is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when BETOPTIC S Ophthalmic Suspension 0.25% is administered to nursing women.
8.4 Pediatric Use
Safety and IOP lowering effect of BETOPTIC S Ophthalmic Suspension 0.25% has been demonstrated in pediatric patients in a 3-month, multicenter, double-masked, active-controlled trial.
8.5 Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients.
- 10 OVERDOSAGE
No information is available on overdosage in humans. The oral LD50 of the drug ranged from 350 - 920 mg/kg in mice and 860 - 1050 mg/kg in rats. The symptoms which might be expected with an overdose of a systemically administered beta-adrenergic receptor inhibitor are bradycardia, hypotension, bronchospasm and acute cardiac failure.
A topical overdose of BETOPTIC S Ophthalmic Suspension 0.25% may be flushed from the eye(s) with warm tap water. If overdose occurs, treatment should be symptomatic and supportive.Close
- 11 DESCRIPTION

- 12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Betaxolol HCl, a cardioselective (beta-1-adrenergic) receptor inhibitor, does not have significant membrane-stabilizing (local anesthetic) activity and is devoid of intrinsic sympathomimetic action. Orally administered beta-adrenergic receptor inhibitors reduce cardiac output in healthy subjects and patients with heart disease. In patients with severe impairment of myocardial function, beta-adrenergic receptor antagonists may inhibit the sympathetic stimulatory effect necessary to maintain adequate cardiac function.
When instilled in the eye, BETOPTIC S Ophthalmic Suspension 0.25% has the action of reducing elevated IOP, whether or not accompanied by glaucoma. Ophthalmic betaxolol has minimal effect on pulmonary and cardiovascular parameters.
Elevated IOP presents a major risk factor in glaucomatous field loss. The higher the level of IOP, the greater the likelihood of optic nerve damage and visual field loss. Betaxolol has the action of reducing elevated as well as normal IOP and the mechanism of ocular hypotensive action appears to be a reduction of aqueous production as demonstrated by tonography and aqueous fluorophotometry.
The onset of action with betaxolol can generally be noted within 30 minutes and the maximum effect can usually be detected 2 hours after topical administration. A single dose provides a 12-hour reduction in IOP. In some patients, the IOP lowering responses to BETOPTIC S may require a few weeks to stabilize. As with any new medication, careful monitoring of patients is advised.
Ophthalmic betaxolol solution at 1% (one drop in each eye) was compared to placebo in a crossover study challenging nine patients with reactive airway disease. Betaxolol HCl had no significant effect on pulmonary function as measured by Forced Expiratory Volume in 1 second (FEV1), Forced Vital Capacity (FVC), FEV1/FVC and was not significantly different from placebo. The action of isoproterenol, a beta stimulant, administered at the end of the study was not inhibited by ophthalmic betaxolol.
No evidence of cardiovascular beta adrenergic-blockade during exercise was observed with betaxolol in a double-masked, crossover study in 24 normal subjects comparing ophthalmic betaxolol and placebo for effects on blood pressure and heart rate.
- 13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Lifetime studies with betaxolol HCl have been completed in mice at oral doses of 6, 20 or 60 mg/kg/day and in rats at 3, 12 or 48 mg/kg/day; betaxolol HCl demonstrated no carcinogenic effect. Higher dose levels were not tested.
In a variety of in vitro and in vivo bacterial and mammalian cell assays, betaxolol HCl was nonmutagenic.
- 14 CLINICAL STUDIES
In controlled, double-masked studies, the magnitude and duration of the ocular hypotensive effect of BETOPTIC S Ophthalmic Suspension 0.25% and BETOPTIC S Ophthalmic Solution 0.5% were clinically equivalent. BETOPTIC S Suspension was significantly more comfortable than BETOPTIC Solution.Close
